The Effect of Suprapubic Magnetic Stimulation in Patients with Neurogenic Detrusor Overactivity

ABSTRACT

PURPOSE: To evaluate the effect of suprapubic magnetic stimulation (SMS) with the use of an arm-type magnetic stimulator for the treatment of patients with neurogenic detrusor overactivity. MATERIALS AND METHODS: Eleven patients with neurogenic detrusor overactivity were enrolled in this study. All patients underwent more than 16 SMS sessions, two times per week, with the use of an arm-type magnetic stimulator. Objective success was defined as a significant reduction (> or =50%) in the total number of leakage episodes per 24 hours, whereas subjective success was defined as the request to continue treatment. RESULTS: Five (71.4%) of 7 patients who had urinary incontinence before treatment reported objective success, and 3 patients showed no incontinence. A total of 6 (75.0%) of 8 patients showed increased average voiding volume. One patient showed an adverse effect of back pain after SMS and dropped out. Seven patients (70.0%) of 10 patients wanted to continue this treatment. They showed significant improvements in frequency/volume chart data, quality of life scores, and urodynamic data. CONCLUSIONS: SMS can be a safe, non-invasive and effective option for the treatment of neurogenic detrusor overactivity.
